Title: Image forming apparatus
Inventor: TAKISHITA SHIGEKI
IPC: G03G15/16
Filed: 2008-05-02
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of preventing fog image failure by decreasing toner transferred to a white part of a recording material or intermediate transfer body from an image carrier when a quantity of charged toner decreases.  <P>SOLUTION: Fog toner that increases in proportion to the longer cumulative time of use is small in a quantity of static charges. Therefore, in the case of the application to a comparatively high transfer bias used for toner that has a normal quantity of static charges, fog toner is subject to a very intense discharge such that the electrification polarity thereof reverses and the fog toner sticks to the photoreceptor drum 1a, making it difficult for the fog toner to be transferred to an intermediate transfer belt 11. With an optical sensor 14a used for measuring the density of a control toner image formed on the photoreceptor drum 1a, the density of fog toner on the photoreceptor drum 1a is measured. If the density of the fog toner exceeds a prescribed value, a transfer bias is increased by prescribed width within a range that permits a decrease in transfer efficiency. Consequently, efficiency in transfer of fog toner is decreased to suppress conspicuous soiling of a base with toner sticking to a white part of an image.  <P>COPYRIGHT: (C)2010,JPO&INPIT
